FIELD: wood-pulp and paper industry.
SUBSTANCE: fibrous material is subject to compression. Pectin-enriched areas in walls of fiber are attenuated selectively due to impregnation of fibrous material with water-based pectines-containing liquid, which results in hydrolysis of pectines. Fibrous material is divided to fibers and refined to produce wood fibrous pulp.
EFFECT: limitation of losses of outcome of fibrous pulp to level at which level decomposition of pectines occurs.
